Pin Function Grouping

A

adrian95

Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, 3v3, gnd_1 gnd_2 etc
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

Yes — from the BME280 datasheet pin table, I’d group each pin exactly once like this:

Table

Functional groupPins
PowerPin 8: VDD — analog supply; Pin 6: VDDIO — digital/interface supply
GroundPin 1: GND, Pin 7: GND
Communication / InterfacePin 2: CSB — chip select; Pin 3: SDI — serial data input / SDA; Pin 4: SCK — serial clock / SCL; Pin 5: SDO — serial data output / I²C address select
No pin is duplicated across groups. For naming, I’d keep both ground pins in the same Ground group but label them separately as GND_1 = pin 1 and GND_2 = pin 7 if the symbol needs unique terminal names.
